2800 HD  (250-3550)         Hard Disk Information       Faxback Doc. # 1850

The computer automatically starts from the hard drive as long as there is 
no diskette in drive A. If the MS-DOS diskette is in drive A, the computer 
will start from drive A.

When you start up from the hard disk, you will begin in DeskMate. If you 
want to start up in MS-DOS instead, run the setup utility and choose MS-DOS 
as the startup environment.

The hard drive is pre-configured with three directories:

  þ Root (\) contains the operating system files needed for startup.
  þ MS-DOS (\dos) contains most of the operating system files.
  þ DeskMate (\desk) contains all the DeskMate applications.

As delivered, the contents of the AUTOEXEC.BAT are as follows:

AUTOEXEC.BAT:

   echo off
   prompt=$p$g
   path c:\desk;c:\dos;c:\
   set dmconfig=c:\DESK
   chkbit
   if not errorlevel 2 goto end
   echo on
   desk
   :end
   echo on

Note: The2800 HD does not comes with a CONFIG.SYS file.

Preparing the Hard Drive:

The hard disk in the Tandy 2800 HD has been initialized at the factory. 
You do not need to perform the processes described here. However, if you 
decide to re-initialize the drive, follow these steps. 

CAUTION: Initializing the disk erases all information on the drive.

Run HSECT to low-level format the drive. THIS WILL ERASE ALL INFORMATION ON 
THE DISK. Make sure you have a copy of your data.

   1.  Insert the MS-DOS disk in drive A.  At the A> prompt type:

       hsect   <ENTER>

   2.  The program prompts you for the drive to format (C/D).

       C       <ENTER>

   3.  The program warns that all data on the drive will be destroyed.

       N       <ENTER> (to exit the program)
       Y       <ENTER> ( to continue>

   4.  Hsect prompts:  "Do you want to flag defective tracks (Y/N)?"

       N       <ENTER>

   5.  Hsect prompts:

       "Enter interleave factor
       Press <enter> to use default value 5. Valid values are 1-8"

       1       <ENTER>

NOTE: DO NOT INTERRUPT HSECT WHILE IT IS FORMATTING THE DRIVE!  

After hsect is complete, use fdisk.

Fdisk creates a partition for MS-DOS on the hard disk.  

CAUTION: Reconfiguring the hard disk with fdisk destroys all existing files.
Be sure you have backed up your data!

   1.  With the MS-DOS disk in drive A, at the dos A> prompt type:
    
       FDISK

   2.  At the Disk Options menu:
       
       1 (DOS partition)   <ENTER>

   3.  At the Create DOS Partition menu:

       1 (Create Primary DOS partition    <ENTER>

   4.  At the Create Primary DOS Partition menu:

       <ENTER>  (to except the default "Y")

Fdisk displays the message "System will now restart".

The format command prepares the hard disk to accept MS-DOS files.  You
must use this command before you can use any disk (hard or floppy) with
the computer.  CAUTION: Formatting destroys any previously existing data
on a disk.

   1.  Place the MS-DOS disk in drive A, and at the A> prompt type:

       FORMAT C: /S   <ENTER>

    2. In response, FORMAT displays the following:

"WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE X: WILL BE LOST!"

       Y  <ENTER>
